C. R. BROWN LOW SAW GUIDE Filed May 5, 1934 Patented Dec. 24, 1935UNITED STATES PATENT OFFICE 4 Claims.

My invention relates to a saw guide and has for its principal object,the provision of a relatively simple, practical and inexpensive devicethat may be conveniently mounted on a work bench, saw horse or angleframe and which functions as a guide for a hand saw while the same isbeing used for sawing pieces of wood or the like and particularly forthe sawing of a piece of Wood at an angle to provide miter joints.

Further objects of my invention are, to provide a saw guide comprising avertically disposed cylindrical member mounted for rotation in a bracketthat is secured to a work bench, saw horse or other frame, said memberhaving a pair of wooden strips that serve as a guide for the saw duringits reciprocating movement and the base or bracket in which the uprightmember is mounted for rotation being provided with simple and eicientmeans for clamping and holding said upright member in diiferentlyadjusted positions so that the saw may be conveniently used in makingangular cuts across the work.

Further objects of my invention are, to provide a saw guide of thecharacter referred to that is very compact and occupies comparativelylittle space when packed for storage or transportation and which sawguide is constructed so as to hold the saw in an out-of-the-Way positiono-n the rear side of the bench or work table while the saw is not beingused.A

With the foregoing and other objects in view my invention consists incertain novel features of construction and arrangements of parts thatwill be hereinafter more fully described and claimed and illustrated inthe accompanying drawing in which:

Fig. 1 is a perspective view of a saw guide of my improved constructionin position for use on a work bench or the like.

Fig. 2 is an enlarged vertical section taken on the line 2-2 of Fig. 1.

Fig. 3 is a vertical cross section taken on the line 3-3 of Fig. 2.

Fig. 4 is an enlarged horizontal section taken on the line 4 4 of Fig.1.

Fig. 5 is an elevational view of the bracket that is attached to thework bench and which serves as a support for the upright rotary sawguide.

Fig. 6 is a horizontal section taken on the line 6-6 of Fig. 5.

Referring by numerals to the accompanying drawing which illustrates apreferred embodiment of my invention, I0 designates the main body of thesaw guide supporting bracket which is in the form of a short tube openat both ends andv projecting inwardly from the lower end of the Wall ofthis tubular body, is a narrow iiange II.

Formed integral with the body of the bracket, are outwardly projectingears I2 that are perforated for the reception of screws I3 that are 5jmay be utilized in adjusting the saw guide so 1551 that the saw may makea through cross cut at ninety degrees or cuts at forty-five degrees forthe purpose of forming a miter joint.

The body of the saw guide comprises a tube I6, preferably of a metal ofsuch diameter as to 20 t within the bracket IU and formed in the wall ofsaid tube are longitudinally disposed diametrically opposite slots I1.These slots are open at the upper end of the tube and they terminate ashort distance above the lower end of the tube. 25

Extending lengthwise through the tubular body I6, is a pair of sawguiding members I8, preferably of wood and which are spaced apart asuilicient distance to accommodate the blade of an ordinary hand saw. 30

A narrow spacing block or strip I9 of cardboard or wood is positionedbetween the lower portions of the guide members I8 and a screw 20 orlike fastening device is utilized for rigidly connecting the lowerportions of guide members 35 I8, said screw passing through the centralportion of spacing member I9.

The vertical edges of the guide members I8 t directly against the innersurface of tube I6 adjacent the edges of the slots I'I and the upperpor- 40 tions of said guide members are secured to the wall of the tubeI6 by screws 2| or like fastening devices.

The slot or kerf between the guide members IB register with the slotsI'I in tube I6 and said slots 45 I'l are substantially wider than theslot or kerf between members I8 so that the teeth of the saw in passingbetween the guide members does not contact with the edges of the metaltube.

In the construction of the tubular member I6, 50 the upper portionsthereof are forced with pressure toward each other after the slots I1have been formed in the tube so that under normal conditions the upperportions of the edges of the slots are positioned immediately adjacenteach 55 other and thus when the wooden guiding strips I8 are inserted inthe tube they will spread the upper portions thereof apart so that theslots I1 are the same width throughout the height of the 5 tube and dueto the resiliency of the metal in the tube the inner faces of the upperportions of the guiding strips I8 will make direct contact with eachother.

As a result of this construction and arrange- 10 ment, the blade of thesaw that passes through the slot or kerf between the guide strips I8will be engaged with a certain degree of pressure that is effective inrmly holding the saw while the same is not in use.

In the use of my improved saw guide the molding or other wooden memberto be cut, is placed on the surface of the work table immediatelyagainst upright stops S that are positioned on the edge of the table tothe sides of the saw guide and the forward end of the saw is inserted inthe lower portion of the slot or kerf between the guiding members I8,then slightly elevated and the saw may then be reciprocated in the usualmanner to cut the molding or other work.

Previous to the cutting of molding or strips placed on the work bench infront of the saw guide, the upright member is rotated so as to hold thesaw at the desired angle and said upright member is then firmly securedto the bracket I0 by tightening the set screw I5.

Thus it will be seen that I have provided a saw guide that is relativelysimple in construction, inexpensive of manufacture and very effective inperforming the functions for which it is intended.

The bracket I0 that supports the saw guide may be conveniently securedto a work bench, saw horse or other supporting fran're and the up-Mright member of the guide may be easily and 40' quickly remo-ved fromor applied to the bracket.

The main body of my improved saw guide is very compact and occupiescomparatively little space in a tool box or when packed for storage ortransportation.

It will be understood that minor changes in the size, form andconstruction of the various parts of my improved saw guide may be madeand substituted for those herein shown and described without departingfrom the spirit of my invention, the scope of which is set forth in theappended claims.

I claim as my invention:

l. In a saw guide, a tube of resilient metal pro- 5 vided withoppositely arranged longitudinally disposed slots, a pair of saw guidingmembers extending lengthwise through said tube to form a saw receivingslot that gradually decreases in width toward its upper end, the upperportions of 10 the tube to the sides of the slot therein exertingpressure upon the saw guiding members so as to converge the same towardtheir upper ends and means for securing said saw guiding members t0 saidtube. l5

2. In a saw guide, a tube oi resilient metal provided with oppositely.arranged longitudinally disposed slots, a pair of saw guiding membersextending lengthwise through said tube the pressure of the upperportions of the tube to the 20 sides of the slot therein exertingpressure against the saw guides to converge the same toward their upperends, means for securing said saw guiding members to said tube and theslot or kerf between said saw guiding members communicating with 25 theslots in said tube.

3. In a saw guide, a bracket having a socket,

a slotted tube of resilient metal having its lower portion removably andadjustably mounted in the socket in said bracket and a slotted saw guide30 extending lengthwise through said slotted tube the pressure of theupper portions of the slotted tube to the sides of the slot thereinexerting pressure on opposite sides of the saw guide to converge thesame toward its upper end. 35

4. In a saw guide, a bracket having a socket, a slotted tube ofresilient metal having its lower portion removably and adjustablymounted in the socket in said bracket, a slotted saw guide extendinglengthwise through said slotted tube, the 40 edges of the slot in thesaw guide communicating with the slots in the tube and those portions ofthe slotted tube to the sides of the slots therein exerting pressureagainst the upper portions of the saw guide to converge same towardtheir up- 45 per ends.
